Grammar Lesson 12~Verbs

Verb phrases with two or more helping verbs always keep a definite order. Most helping verbs can combine with other helping verbs but will not combine with all of them. Look at the examples below which are good combinations.
is being said, has been said, will be said, could have been said, may have said, had been said.
Now arrange the following helping verbs with the word in parentheses into a verb phrase. One of the helping verbs will not combine and must be left out.
Example: was, have, may (gone) = may have gone – was will not combine in this group.
